摘要： Object: Rear wheels are returned to central orientations when a rear wheel steering mechanism of 4WS system fails to operate. Required drive power is minimized and the apparatus is reduced in size.
Arrangement: A main motor M1 is coupled to a steering shaft 1 through a drive transmitting mechanism 1a, 5a, 5b and 6a, and an auxiliary electric motor M2 is coupled to a drive shaft 6 through a gear mechanism 9, 12, 8a, 7 which includes a solenoid operated clutch CL. The motor M2 is normally disengaged from the drive shaft, but upon detecting the occurrence of a failure, the clutch is activated and the motor M2 is set in operation for returning the steered position of the rear wheels to the center.

摘要： In a hydraulic active suspension system, a plurality of actuators (1FR,1FL,1RR,1RL) having working fluid chambers (2FR,2FL,2RR,2RL) are provided corresponding to vehicle wheels. Each actuator is adapted to increase and decrease vehicle height in response to the pressure within its working chamber, which is controlled by a pressure control device. Vehicle speed and lateral acceleration are detected by corresponding sensors (234,238). A control device is further provided for controlling the pressure control device by compensating values determined based upon the lateral acceleration detected. The control device is adapted to reduce the compensating values in magnitude when the vehicle speed is lower than a predeterminate value under which the lateral acceleration sensor sometimes detects a flase lateral acceleration, thereby reduce the possibility that the vehicle body may generate an unpleasant roll due to the erroneous control on the pressures within the working fluid chambers based upon a flase lateral acceleration.

摘要： A pressure control valve (80 fr) delivers a pressure which is proportional to a current level chosen to energize a solenoid (99) therein to a shock absorber of a suspension. A spool (90) in the valve (80 fr) has an annular groove (91) for communicating an output port (84) to a high pressure port (87) or a low pressure port (85) selectively. There are conical surfaces (91a) or inclined surfaces at edges of lands adjacent to the groove (91), which incline from annular surfaces of the lands toward the bottom of the groove. The inclined surfaces slow down a change of the flow rate from the high pressure port to the output port (84) and from the output port to the low pressure port (85) when the annular groove (91) communicates with the high pressure port (87) and the low pressure port (85) respectively.

Each actuator is adapted to increase and decrease vehicle height in response to the pressure within its working chamber, which is controlled by a pressure control device. Vehicle speed and vehicle heights at the locations corresponding to the vehicle wheels are detected by corresponding sensors (199FR) to (199RL). A control device is further provided for controlling the pressure control device so that the pressures within the working fluid chambers may be their desired pressures determined by, at least, the sum of the first controlling quantities corresponding to the differences between the actual vehicle heights detected and the associated desired vehicle heights and the second controlling quantities corresponding to the changing amounts of the vehicle height differences. The second controlling quantities are so set that the higher the vehicle speed is, the higher the second quantities are in magnitude, so as to enhance the controllability and stability of the vehicle under higher vehicle speed conditions and to ensure better comfortability of the vehicle under lower vehicle speed conditions.
